Error: Virtual Machine could not be started because the hypervisor is not running

I recently changed my 500GB SATA disk to 1TB SSD on my laptop using Samsung Magician to copy the data from SATA to SSD. After completing the task, I noticed a better performance but when I opened Hyper-V Manager, and try to start the virtual systems, I got the error below.

Virtual Machine could not be started because the hypervisor is not running”..
To resolve this issue, complete the following steps:
1. Run the following command on the system that host the Hyper-V: bcdedit /set hypervisorlaunchtype Auto
2. Reboot the system
3. Log on to the system, open Hyper-V Manager, you should be able to start the Virtual system now.
